Summary
The Miniscrew Implant Supported Distalization System (MISDS) achieved nearly bodily distal movement of posterior teeth. The Bone-Anchored Pendulum Appliance (BAPA) resulted in significant distal tipping of maxillary molars.
Area of Science:
- Orthodontics
- Dental Implantology
- Craniofacial Growth
Background:
- Angle Class II malocclusion requires effective treatment strategies.
- Distalization of posterior teeth is a common orthodontic goal.
- Absolute anchorage systems are crucial for predictable tooth movement.
Purpose of the Study:
- Compare the skeletal, dental, and soft tissue effects of MISDS and BAPA.
- Evaluate the efficacy of two absolute anchorage systems for posterior tooth distalization.
- Analyze cephalometric changes following treatment with MISDS and BAPA.
Main Methods:
- Retrospective cephalometric analysis of 28 Angle Class II patients.
- 14 patients treated with MISDS, 14 with BAPA.
- Paired and unpaired t-tests for statistical evaluation.
Main Results:
- Both MISDS and BAPA successfully achieved posterior tooth distalization.
- MISDS resulted in nearly bodily distal movement.
- BAPA showed significant distal tipping of upper first molars (P < .001).
Conclusions:
- Both MISDS and BAPA offer absolute anchorage for distalization.
- MISDS provides more translatory distal movement.
- BAPA is associated with substantial distal tipping of maxillary molars.
